Step 1

With your original seatpost set to your desired ride height, measure from the top of the seat collar to the center of the saddle rails. This will be Measurement "A".

Compare measurement "A" to the charts below to determine the maximum travel Transfer Seatpost that will work for your application. 

Measurement A Transfer Travel (Internal Routing)
233.2mm-403.7mm 175mm
209.5mm-355mm 150mm
185.5mm-305mm 125mm
160.5mm-255mm 100mm

 

Measurement A Transfer Travel (External Routing)
248.1mm-410.2mm 175mm
224.4mm-359.9mm 150mm
199.5mm-310mm 125mm
174.3mm-259.8mm 100mm

If your measurement "A" does not fall within any of the tables in step 1 above, please contact FOX.

If your measurement "A" falls within the tables in step 1 above, continue below to check for proper insertion clearance within the frames seat tube.

Step 2

You will also need to check that the FOX Transfer Seatpost will fit deep enough into your frame without contacting any internal part within the frame.

Carefully insert your original seatpost fully into the frame until it contacts any obstruction. This could be a suspension pivot or a bend in the seat tube. Measure from the top of the seat collar to the center of the saddle rails again. This will be Measurement "B".

Step 3

Remove the original seatpost and measure from the bottom of the post to the center of the saddle rails. This will be measurement "C". 

Subtract measurement "B" from measurement "C" to determine measurement "D".

Step 4

Add measurement "A" to measurement "D".

Compare "A" + "D" to the charts below to verify that at your desired saddle height, the FOX Transfer will be able to insert deep enough into your frame without contacting any internal part within the frame. 

Your "A" + "D" value must be equal to or greater than the number in the table below for that specific post to work with your frame.

Measurement
A + D
Transfer Travel
(Internal Routing)
534mm+ 175mm
485mm+ 150mm
434mm+ 125mm
384mm+ 100mm

 

Measurement
A + D

Transfer Travel
(External Routing)

510mm+ 175mm
461mm+ 150mm
411mm+ 125mm
361mm+ 100mm

If your measurement "A"+"D" does not fall within any of the tables in step 4 above, please contact FOX.

Troubleshooting Guide

Symptom Possible Cause Check, in this order: If yes, then adjust this:
Creeps down when sitting on the post Too much cable tension Is there any freeplay in the lever (a.k.a. slack in the cable)? Turn lever barrel adjuster to the point where the tip of the lever can freely move 2-5mm
  Is something preventing your lever from returning freely or completely? Check lever function, visually ensure no damage, fix/replace as needed.
Is your cable too short, or catching on something?  Does the post only creep with the bars turned? Fix/replace inner cable and housing as necessary
Is the cable pinched in the frame?  If so- especially if the saddle height has been raised- the cable could be partially pulled.   Loosen the seat post clamp, lower the post in the frame ~10mm, re-clamp - is it still a problem?
Is the cable kinked or sharply bent in the frame?  Does the post creep when removed from the bike? Fix/replace inner cable and housing as necessary.  Make sure you do not force the post into the frame as this can bend the cable (especially if there is a bend or other interruption inside the frame)
Slow to extend through entire stroke Not enough cable tension (cable isn't being fully pulled) Is the seatpost clamp gap aligned with the slot in the seattube?  Rotate clamp so that gap is 180 degrees from slot in seattube.
  Does this only happen in cold temps, or after the post has been stored in the down position?  A slower return is to be expected in cold temps.  Cycling the post up and down by hand several times can help warm things up.
Is there too much freeplay in the lever (a.k.a. slack in the cable)? Turn lever barrel adjuster to the point where the tip of the lever can freely move 2-5mm
Is there a broken barrel adjuster on your lever (causing too much slack in the cable)? Replace adjuster or lever as necessary
Is the seatpost clamp bolt too tight?  Loosen it completely and check again.  Does the post return better? Clean post and frame seat tube with alcohol, apply friction paste to inside of frame and bottom of post.  Tighten seatpost clamp to the minimum torque required to avoid the post slipping in the frame.  Increase to the point at which you can start to feel a tight spot when moving the post up and down, and then back off 0.5 N-m.  Do not torque above 5 N-m.
Is this fixed by re-lubricating the seal and bushings?   Try using a thin non-metallic zip tie (or similar) to lightly lift the wiper seal lip and add a drop of Float Fluid.  Do this at 2 places around the post, 180-deg opposite each other.  On MY2021 and newer, you can also do this by unthreading the post collar, lubricating, and then torqueing the collar to 12 ft-lb.
Is the cable kinked or sharply bent in the frame?  Is the post slow to return when removed from the bike? Fix/replace inner cable and housing as necessary.  Make sure you do not force the post into the frame as this can bend the cable (especially if there is a bend or other interruption inside the frame)
Check the post off the bike, with no cable attached, by pressing the lever on the bottom of the post with your thumb.  Does it still return slowly?  If not, re-check the items above. If you've checked the items above, and the post isn't working properly when removed from the bike, please contact your local FOX Service Center to arrange for diagnosis and repair.

Slow return at a only certain point in travel, or only at the end of the stroke, or you can feel a 'tight spot' when pushing the post down Binding due to too much torque on seatpost clamp Is the seatpost clamp gap aligned with the slot in the seattube?  Rotate clamp so that gap is 180 degrees from slot in seattube.
  Does this only happen in cold temps, or after the post has been stored in the down position?  A slower return is to be expected in cold temps.  Cycling the post up and down by hand several times can help warm things up.
